What is perturbation? Simply put, perturbation refers to a small change or disturbance in a system. This concept is used in various fields like physics, astronomy, and even biology. Imagine a calm pond; throwing a pebble into it creates ripples. Those ripples are perturbations. In space, the gravitational pull from a nearby planet can cause a perturbation in another planet's orbit. In biology, a sudden change in temperature can perturb a cell's normal functions. Understanding perturbations helps scientists predict how systems react to changes, making it a crucial concept in many scientific studies.
